Re: [Nagios-users] random character appended to NRPE output
Hi, I also have this, and think this is a bug. I reported this already to the dev list, but don’t know if someone saw mu mail. Still, since I suspected this had to do with string ending, I added the following at the end of all my test scripts : /usr/bin/printf \0 I did this because I think strings end with a zero char in C, so I thought it would be worth trying printing one manually.

Re: [Nagios-users] Go to map button
Alex, I am not sure, but, why not rename the extinfo.cgi file in your SOURCE tree and re-run 'make' to recompile the file from the source (extinfo.c). I'm assuming you still have the source and not done a 'make clean', 'make distclean' etc... all of which is probably beyond the scope of the Nagios list.

Re: [Nagios-users] Problem with some NSCA packets getting corrupted on 64-bit SLES 10
Brian,
You beat me to the punch. After a few days of trying to figure out the
pattern, I found this was only happening when the distributed nodes were
trying to do host checks. Further discover revealed that we were using
'fping' to check host reachability which did include a ',' in the
output. The send shell script I was using at the time passed -d ','
to send_nsca to use as a delimiter.
So while the actual host check was sending only 3 fields to the
send_service_check script, the arguments to send_nsca were causing it to
be broken into 4 fields so the NSCA daemon assumed it was a service
check.
Not that it matter which I use, but I switched over to use Ethan's
script. I guess when no arguments are passed to send_nsca, it breaks on
a tab as a delimiter. Anyway, that part of my migration has been
working fine.
Glad to see the whole 64-bit business was a red herring in my setup
(whew!).
Thanks for your help.
Mark

Show us your ocsp_command and ochp_command mappings. Are you calling a
piped command from checkcommands.cfg or calling an external shell
script?
I guarantee you the comma (,) in results is being mapped into a field
delimiter, which confuses nscad(8).

I've recently begun an effort to move our Nagios installation to a
distributed architecture from a centralized one. I had previous used
NSCA only for a very few passive checks and it works fine on a 32-bit
Red Hat AS 3 platform (the centralized server).
In testing on a distributed architecture (which is 64-bit Suse Linux
Enterprise Server (SLES) 10), I seem to have a problem with NSCA.
(Note
that all Nagios and NSCA binaries and libraries were recompiled on the
64-bit platform).
After I broke out all the checks to have 2 separate distributed nodes
send to a central server, I saw a few messages like this one in the
nagios.log file:
[1200583727] Warning: Passive check result was received for service
'0'
on host 'HOSTXXX', but the service could not be found!
but only about every 1 out of 10 or maybe 20 results was doing this.
That is, the rest of the results were being correctly shown as
EXTERNAL
COMMAND and all expected NSCA fields came up correctly (hostname,
service desc, check result, text output).
I started having the send_nsca script from the distbributed nodes
log
what they were sending to a file. When I correlate what they're
sending
with what the NSCA daemon thinks it's receiving, the client is still
sending the correct 4 fields, but it's as if the NSCA daemon is
dropping
the 2nd field (service desc) and replacing it with the check result
field. So ultimately, it thinks the service name is '0'.
I can't see that this matches a pattern (i.e. always on the same hosts
or same service checks). All I've seen so far is that it happens
whether I run NSCA as --single or --daemon. It also happens even if I
turn off one of the distributed nodes (that is, I can't see it being
volume related).
I have turned on debugging in the NSCA daemon to see what it thinks
it's
getting and it echoes what the nagios.log shows:
SERVICE CHECK - Host Name: 'HOSTXXX', Service Description: '0',
Return
Code: '0', Output: ' rta=0.14 ms)'
Again, maybe only 1 out of 10. Ultimately, this causes the server to
run an active check as it thinks it never got a result from the
distbributed node.
I'm still trying to dig deeper, but it seems to me that this is
increasingly pointing to some issue with 64-bit SLES. Or perhaps some
variable type in NSCA daemon that's not quite right for 64-bit. It's
hard to tell with its intermittent nature and the fact that I have yet
to discover a pattern.
Has anyone seen anything like this before?
Thanks
Mark

[Nagios-users] Problem with high latencies after going distributed
As I'd mentioned in a previous message, I'm in the process of converting
from a centralized
Nagios 2.10 setup all running on a single host to a distributed setup
running on at least 3
hosts (3 to start anyway). The centralized setup has 572 hosts and 2900
services 99.9% of which are active checks.
My approach when going passive was to group the checks so that some ran
on the first distributed node and some ran on the second node. The
central server will do freshness
checking and run an active check if it fails to get a check back from a
distributed node
after 20 minutes (virtually all checks run at 15 minute intervals or
less).
Our old centralized server reports the following via nagiostats:
Active Service Latency: 0.000 / 9.129 / 0.833 sec
Active Service Execution Time:0.037 / 10.045 / 0.227 sec
I started noticing a fair number of checks going stale on the new
reporting server and
that server would then run those service checks actively. I could see
no reason for this.
When I had a look at the distributed nodes, I saw:
Distributed Node 1(min/max/avg)
Active Service Latency: 0.000 / 7267.198 /
4241.019 sec
Active Service Execution Time:0.000 / 60.014 / 0.651 sec
Distributed Node 2(min/max/avg)
Active Service Latency: 0.000 / 11475.901 /
6393.641 sec
Active Service Execution Time:0.000 / 60.018 / 0.593 sec
Wow.
I reviewed the performance doc for Nagios 2.x yet again and I'm not
finding anything there
that I'm not doing that would affect latencies this much. These boxes
are dedicated to Nagios
so there's no other application competing for resources. They're on the
same subnet.
I run a few perl checks, but that would be a very small percentage of my
checks. The
distributed nodes are newer and have more resources (faster CPU, at
least as much memory)
as the old standalone box.
The only thing I can think of that could be unusual is that both
distributed nodes know about
all hosts and services. I have created a configuration whereby
hosts/services that are not
to be checked by node 1 are given a template that looks like:
define service {
namenagios-dist-check-service
freshness_threshold 1200
active_checks_enabled 1
check_freshness 0
check_period24x7
event_handler_enabled 0
flap_detection_enabled 0
notifications_enabled 0
obsess_over_service 1
passive_checks_enabled 0
process_perf_data 0
register0
}
define service {
namenagios-dist-nocheck-service
freshness_threshold 1200
active_checks_enabled 0
check_freshness 0
check_periodnone
event_handler_enabled 0
flap_detection_enabled 0
notifications_enabled 0
obsess_over_service 0
passive_checks_enabled 0
process_perf_data 0
register0
}
So services on node1 that are supposed to be run, get the
nagios-dist-check-service template
and those that should not, get the nagios-dist-nocheck-service template.
Is there something about Nagios that I don't understand that would cause
a lot of disabled
service checks to shoot latencies way up? Is something else going on
here?
Here's my output of nagios -s on one of the nodes (both yield similar
output and are configured similarly):

The command line I run on the shell is: ./usr/local/nagios/libexec/check_http -H www4.somehost.com.br -u /monitor/billing.asmx/isFunctional?idCarrier=6 -s 'boolean xmlns=http://www.somehost.com.br/;true/boolean' My nightmare starts when I put the line on services.cfg It seems like nagios don't understand what I put on services.cfg (or I'm giving the wrong syntax). The check_command line on services.cfg is: check_http!www4.somehost.com.br!/monitor/billingvpn.asmx/isFunctional?idCarrier=6!'boolean xmlns=http://www.somehost.com.br/;true/boolean' The commands.cfg check_http line is: check_http -H $HOSTADDRESS$ $ARG1$ $ARG2$ I've tried already putting -u and -s before $ARG1$ and $ARG2$... But no changes has occured. I've tried also putting just -s before $ARG2$... And nothing changed. The www4.somehost.com.br is the virtualhost -H option /monitor/billingvpn.asmx/isFunctional?idCarrier=6 is the URL -u option and 'boolean xmlns=http://www.somehost.com.br/;true/boolean' is the string expected, -s option. The above command works perfectly. If I change anything after -s the expected string changes and the service status changes to CRITICAL, indicating that he command works normally. But Nagios daemon couldn't show the same... I don't know what's happening... If someone have some hint to give me... I'll apretiate.

Re: [Nagios-users] nagios.cmd over nfs
AFAIK, You cannot use a FIFO (pipe) over NFS. The pipe refers to not a file but a kernel IPC method. So a FIFO created on the NFS server is known to the nfs server and not the client system.

Re: [Nagios-users] Strange think
Hi all!
I've tried what hugo has poted.
I've got it workin using the following lines on commands.cfg
check_http -H $ARG1$ -u $ARG2$ -s $ARG3$
Only with that syntax I could got the webservices check fair!
Thanks for all messages!!

It seem you are mixing things in a odd manner.
I would recommend to define the command with:
define command{
command_namecheck_http_reply
command_line$USER1$/check_http -I $HOSTADDRESS$ -H $ARG1$ -u
$ARG2$
- -s $ARG3$
}
Then define the service with:
check_http_reply!www.somehost.com.br!/heartbeat.asmx/Web!'boolean
xmlns=http://www.somehost.com.br/;true/boolean'
I would never try to mix the arguments the way you did.

Re: [Nagios-users] Problem with high latencies after going distributed
As I'd mentioned in a previous message, I'm in the process of
converting
from a centralized
Nagios 2.10 setup all running on a single host to a distributed setup
running on at least 3
hosts (3 to start anyway). The centralized setup has 572 hosts and
2900
services 99.9% of which are active checks.
...
Active Service Latency: 0.000 / 7267.198 /
4241.019 sec
This isn't much help, but...
We've just done exactly the same (Nagios 2.9), and we have a comparable
size of system (actually a bit larger - 713 hosts, 5834 services).
After going distributed, we too have this insanely high latency on the
satellites.
The only possible cause is the OCSP command slowing things down somehow.
This is using the supplied send_nsca call to send the status off to the
central server...
define command {
command_namerelay
command_line$USER1$/submit_check_result $HOSTNAME$
$SERVICEDESC$ $SERVICESTATEID$ $SERVICEOUTPUT$
}
So it should work. I guess things would be better if it packaged the
updates up into batches, although it cant do that normally.
I think it might be better to make the OCSP command just dump the status
to a file, and then have a cronjob every 60 seconds that reads the file
and sends the statuses off as a batch. I will try this here, when I get
the chance.

But if the submit_check_result is running slowly, that would only affect
the service
execution time wouldn't it? My understanding of check latency is that
it's the difference
in time between when Nagios schedules a check to run versus the time
that the check
actually starts to execute.
But maybe I'm misunderstanding something here. When it comes to working
with Nagios, I
tend to learn the most when I have the biggest problems :-).
Do you do the same thing I mentioned where you define all the checks on
both distributed
nodes, but disable checks on complimentary halves of those checks on
each node?
Thanks

Re: [Nagios-users] Problem with high latencies after going distributed

But if the submit_check_result is running slowly, that would only affect the service execution time wouldn't it? My understanding of check latency is that it's the difference in time between when Nagios schedules a check to run versus the time that the check actually starts to execute. If the scheduler gets behind, then the latency increases as it runs the service checks in order of the scheduler. It is possible that the OSCP handler is run SERIALLY with service checks (as the host checks are done in 1.x) and is therefore holding up service checks, just like you'd see if you had a lot of down hosts and a long-running host check command. But maybe I'm misunderstanding something here. When it comes to working with Nagios, I tend to learn the most when I have the biggest problems Don't we all :-/. The latency effect of non-parallel host checks was a nasty surprise to me. Do you do the same thing I mentioned where you define all the checks on both distributed nodes, but disable checks on complimentary halves of those checks on each node? Yes. However, I can't always set the freshness checking because some of our checks are every 4 hours, although most are at a sub 15min interval. We have a complex configuration tool that builds our whole distributed Nagios/MRTG configuration set from templates so I can't hand-hack the config files either. I have now set up one of our distributed nodes to batch the NSCA messages, and will see if the latency increases overnight (so far, it looks good). To do this, I just changed submit_check_result to only append to a file, then added a Nagios every-minute cronjob to cat the contents of this file into send_nsca (actually, there are a few more steps to ensure data integrity and checks, but that's basically it). The upshot is that some checks may be delayed by up to a minute, and we're dependent on cron, but the OCSP command exits very fast. Let me know if you want a copy of the two scripts I used to achieve this. Steve - This SF.net email is sponsored by: Microsoft Defy all challenges.

Subject: RE: [Nagios-users] Problem with high latencies after
going distributed
We've just done exactly the same (Nagios 2.9), and we have a comparable
size of system (actually a bit larger - 713 hosts, 5834 services).
After going distributed, we too have this insanely high latency on the
satellites.
The only possible cause is the OCSP command slowing things
down somehow.
This is using the supplied send_nsca call to send the status off to the
central server...
define command {
command_namerelay
command_line$USER1$/submit_check_result $HOSTNAME$
$SERVICEDESC$ $SERVICESTATEID$ $SERVICEOUTPUT$
}
So it should work. I guess things would be better if it packaged the
updates up into batches, although it cant do that normally.
I think it might be better to make the OCSP command just dump
the status
to a file, and then have a cronjob every 60 seconds that reads the file
and sends the statuses off as a batch. I will try this here,
when I get
the chance.

But if the submit_check_result is running slowly, that would only affect
the service
execution time wouldn't it? My understanding of check latency is that
it's the difference
in time between when Nagios schedules a check to run versus the time
that the check
actually starts to execute.
You're right, but you're just missing one detail. Nagios runs checks in
parallel and then reaps all the service results at once. While it's
reaping it can't schedule other checks and it is in the reaping state
that Nagios runs host check, event handlers, performance data commands
and oc[hs]p commands. All this is done serially and can slow down
significantly each service reaping run and thus delay the execution of
further checks.
I although I never built a distributed system, I designed mine to be
easily distributed. Moreover, I used a technique I developed for
latency-free performance-data processing (That I still heavily use BTW)
to create a way to distribute check results to to a distributed central
server in the same latency-free way (Was more like a fun project as I
don't use it myself yet).
Basically you use the host/service performance data files to get the
data, but instead of writing to a file you write it to a named pipe
(fifo). That pipe is then read by a high-performance non-blocking
event-based Perl daemon (yeah I know that looks like marketing terms,
but I can explain further each of them if you like) that forks send_nsca
processes to send results in bulk (normally every few seconds though).
So Nagios doesn't even loose time rotating a file and all your checks
are transmitted almost instantly. See this wiki page for details and code:

Re: [Nagios-users] nagios.cmd over nfs
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 On 22/01/08 03:38 PM, [EMAIL PROTECTED] wrote: ... not so much It solves the web page spinning, but since nagios never picks up the data nothing happens. Yep. As it was already said on the thread fifos only works locally. It implemented in the kernel, not in the FS code. The FS is only involved in giving it a name and permissions (and this trivial task is properly implemented by NFS: each server can use the pipe ... locally). A trivial (hacky) workaround could be using Netcat (nc): On the webserver: cat /path/to/nagios.cmd | nc nagios_host some_port On the Nagios server: nc -lp some_port /path/to/nagios.cmd Since NC can die you should ideally run in with Daniel J Bernstein's Daemontools: http://cr.yp.to/daemontools.html Also try in UDP mode (nc -u host post / nc -lup port) if you have problems. The solution I'd go for though would be using Perl daemons for relaying the commands using code similar to these daemons: http://www.nagioscommunity.org/wiki/index.php/OCP_Daemon#OCP_daemon_code http://nagiosexchange.altinity.org/nagiosexchange/NPDaemon/ It requires good Perl knowledge, especially since these daemons doesn't include any non-blocking sending function. Since the command pipe isn't much solicited you can just go blocking too (while (FIFO)/blocking send on the web server, blocking listen/blocking write to the nagios server), but make sure you implement timeouts with alarm() in the network code to avoid jamming there.
